For memcpy tests, the dmatest module provides a good example. See drivers/dma/dmatest.c for the source. For more advanced usage, search the archives for: [PATCH RFCv3 0/2] CARMA Board Support Those drivers use some of the advanced features of the DMAEngine API to transfer data from an FPGA into RAM.
